## How the post analyzer works {#how-it-works}

You paste your draft into the tool, with nothing to connect and nothing published. In under 10 seconds, the analyzer returns a full diagnostic built around four dimensions, plus a concrete list of strengths and weaknesses.

Each dimension is scored independently, then combined into an overall virality score. The point isn't a score for its own sake, it's to tell you **what to change before you publish**.

### The virality score {#virality-score}

This is the headline indicator. It aggregates **12 quality rules** (hook, length, readability, formatting, a clear call to react...) and **21 writing tactics** detected in your text. The higher the score, the more your post matches the patterns of high-performing publications.

### The controversy score {#controversy-score}

Measured controversy is one of the strongest comment drivers on LinkedIn. The tool gauges how much of a stance your post takes, sparing you both the lukewarm post that engages no one and the divisive post that crosses the line.

### Sentiment analysis {#sentiment-analysis}

The analyzer identifies your post's dominant tone (positive, negative, neutral). You confirm at a glance that the emotion you convey matches your intent.

### The tactics X-ray {#tactics-xray}

The tool surfaces the **21 tactics** it recognizes in your text: storytelling, open question, shock number, list, social proof, and more. You instantly see which levers you already use and which ones you could add.

## What data the analysis relies on {#data}

The analyzer's rules and tactics don't come from thin air: they're calibrated on a base of **1 million analyzed LinkedIn posts**. That base is what separates what truly correlates with engagement from what's just folklore.

The free analyzer is deliberately simpler than LinkPost's full engine. It gives you the essentials so you never publish blind, without drowning you in metrics.

## How to read and improve your score {#interpret-improve}

A low score isn't a punishment, it's a roadmap. Always start with the **hook**: the first line decides whether your post is read or skipped. Then check formatting (short sentences, line breaks, one idea per block) and whether your angle is sharp enough to make people react.

Re-analyze after each edit. Within a few iterations, you learn the patterns that lift your score, and you end up writing them by instinct.

## From free analysis to generating with LinkPost {#toward-linkpost}

The analyzer scores a post you already wrote. LinkPost goes further: it **generates 25 variants per topic**, scores **300+ factors** with a **33-criteria** virality prediction and **27 factors personalized** to your style, then lets you schedule and analyze your publications.

There's no free trial of the full product: the post analyzer is the free tool, and LinkPost is the next step when you want to write better, faster, and measure your results over time.

## What the analyzer measures, dimension by dimension {#data}

> The five dimensions of the diagnostic from the free analyzer.

| Dimension | What it evaluates | Why it matters |
|---|---|---|
| Virality score | Reach potential (12 rules + 21 tactics) | Anticipates a flop before publishing |
| Controversy score | How much of a stance you take | Measured controversy drives comments |
| Sentiment analysis | The post's dominant tone | Aligns emotion with your intent |
| Tactics X-ray | 21 writing tactics detected | Shows which levers you already use |
| Strengths and weaknesses | What to keep and what to fix | Gives a clear improvement to-do list |

> A post isn't viral by accident: it combines a hook that stops the scroll, a format readable in two seconds, and a stance that makes people want to comment.
